Abstract: Selective compliance in up to six degrees of freedom in a magnetically levitated fine motion device, or robot wrist, with limited motion in X, Y, Z, ROLL, PITCH, YAW, is provided by controlled actuation currents applied to six electrodynamic forcer elements (5). The wrist has a stator support base (9) defining a dual periphery, carrying a number of stator magnet units (4). A shell flotor unit nests within the stator support base dual periphery, and carries forcer coils at locations corresponding to respective magnet units (4). The magnet unit (4) and related flotor coil (3) form a forcer element (5). There are a number of forcer elements (5). The vector sum of all the translational forces and rotational torques established at the forcer elements determines the X, Y, Z, ROLL, PITCH, YAW motion of the flotor. The flotor carries an end effector which may be a tool. Position and orientation of the flotor is monitored by light emitting diodes (7) and lateral effect colls. Coil currents are controlled as a composite of present position, desired final position, and desired compliance. As the fine motion device approaches its final position, the control unit changes forcer coil current patterns at various sets of forcer elements (5), to provide selected compliance in one or more degrees of freedom while approaching and finally while maintaining the desired position. Cooling is provided as needed; docking and locking provision is made to allow de-energizing the coils for cooling, motion of the base, or shutdown.

Abstract: A pump control system is described in which the pumping mechanism causes corresponding movement of a pair of capacitor plates (64,66). The plates are energized by an a.c. signal, and the signal produced by the plates is amplitude detected, with the amplitude modulation representing pumping force. The pumping force is converted to pumping pressure. The pumping pressure peak during pumping and the pressure minimum during filling are detected to determine the portion of a pumping cycle required to make the transition between these two pressure levels. The difference between the two pressure levels divided by the transition portion of the pumping cycle gives a measure of the compliance of the pump chamber. The ratio of the compliance measure to the total cycle, when multiplied by the nominal chamber volume, gives a measure of unpumped volume, which is subtracted from the nominal volume to give the volume actually pumped during a pump cycle. The volume pumped is compared with a desired flow rate to determine a speed control value for the motor of the pumping mechanism. A motor control signal is developed by subtracting from a constant number a value which is a factor of the speed control value and the position of the motor.

Abstract: A rectifier circuit having a rectifier (D4) allowing current to flow in a forward direction to an output (VOUT). A saturable inductor (L3) in series with the rectifier (D4) blocks reverse recovery rectifier current and directs it to an inductor (L4), the energy stored in that inductor re-setting the saturable inductor (L3) to allow subsequent flow of current in the forward direction to the rectifier (D4). A capacitor (C2) absorbs surplus energy from the inductor (L4) and a rectifier (D5) guides that surplus energy to the output (VOUT). This rectifier circuit is particularly useful as part of a convertor where an electronic switch repeatedly switches current through an inductor (L1) and the energy from the inductor (L1) is delivered to the output (VOUT) via the rectifier circuit.
